格式日期Java [英] Format Date Java

问题描述

如何格式化一个这样的字符串

How to format a string that looks like this

Sat Dec 08 00:00:00 JST 2012

Sat Dec 08 00:00:00 JST 2012

into yyyy-mm-dd ie

into yyyy-mm-dd i.e.

2012-12- 08

2012-12-08

浏览 web ，我发现这段代码：

From browsing the web, I found this piece of code:

SimpleDateFormat formatter = new SimpleDateFormat("dd-MMM-yyyy");
    String dateInString = "Sat Dec 08 00:00:00 JST 2012";

    try {

        Date date = formatter.parse(dateInString);
        System.out.println(date);
        System.out.println(formatter.format(date));

    } catch (ParseException e) {
        e.printStackTrace();
    }

但是，我无法修改它接受第一行（Sat Dec 08 00:00:00 JST 2012）作为字符串和格式，以yyyy-mm-dd格式。

However, I am unable to modify it to accept the first line (Sat Dec 08 00:00:00 JST 2012) as a string and format that into the yyyy-mm-dd format.

我该怎么办？我应该尝试修改吗？或者尝试另一种方法？

What should I do about this? Should I be attempting to modify this? Or try another approach altogether?

更新：我使用这个从你的答案（得到错误：不可稀释的日期：星期六12月08 00:00:00 JST 2012）

Update: I'm using this from your answers (getting error: Unparseable date: "Sat Dec 08 00:00:00 JST 2012")

public static void main(String[] args) throws ParseException{
        SimpleDateFormat srcFormatter = new SimpleDateFormat("EEE MMM dd HH:mm:ss z yyyy", Locale.JAPANESE);
        SimpleDateFormat destFormatter = new SimpleDateFormat("dd-MMM-yyyy", Locale.JAPANESE);
        Date date = srcFormatter.parse("Sat Dec 08 00:00:00 JST 2012");
        String destDateString = destFormatter.format(date);
       /* String dateInString = "Sat Dec 08 00:00:00 JST 2012";*/
        System.out.println(destDateString);

        /*try {

            Date date = formatter.parse(dateInString);
            System.out.println(date);
            System.out.println(formatter.format(date));

        } catch (ParseException e) {
            e.printStackTrace();
        }*/
    }
}

推荐答案

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH);
String dateInString = "Wed Oct 16 00:00:00 CEST 2013";
    try {
        SimpleDateFormat parse = new SimpleDateFormat("EEE MMM dd HH:mm:ss Z yyyy", Locale.ENGLISH);
        Date date = parse.parse(dateInString);
        System.out.println(date);
        System.out.println(formatter.format(date));

    } catch (ParseException e) {
        e.printStackTrace();
    }

将您的格式更改为新的SimpleDateFormat（yyyy -MM-dd，Locale.ENGLISH）;

谢谢..
